Nice build, the author uses old inner tubes, dowl rod, and aluminum pipe (oh and paracord for the handle). Me, I like the build but cutting the metal pipe sounds a bit tedious to me for something like this. Maybe PVC with a coat of paint would work better? Either way, these make nice simple (and cheap) water proof containers for camping or boating….hum…maybe to put a cellphone in while boating?
